> It also states one line before

I know and I believe there is a purpose to be exactly after that line. Writing only simple code is not enough. If you write everything in a simple manner your code will most likely be complicated, that's exactly why you have next - complex is better than complicated.

I see this feature the same way as comprehensions, scary and complex at first, but once you learn it you would wish anyone would use it.
